Be it known that we,.MAx1MIL1AN CHARLES SOHWEINERT, residing 1n Vest Hoboken, 1n

the county of 'I-ludson and State of New KRAFT, residing in the J ersey, and HENRY '1.

county of Kings, city and State of New York, both citizens of the United States, have jointly invented certain new and useful Improvements in Socket Members for Water-Bags, of which the following is a specificatiom This invention relates to water bags or similar articles of the type in which thebag is molded in. one piece as distinguished from those bags which are formed ofp'a number of pieces of rubber cloth vulcanized together.

' In the'manufacture of molded water bags a suitable mold is dipped in a rubber solution a sufiicient number of" times tobuild u .a wall .of proper thickness. After the last coat is dried themold with its rubber covering is placed in the vulcanizing chamber so that the bag vulcanizes upon the mold. In this type of bag in order that the mold may be removed after vulcanization it is necessary to provide the bag with a comparatively large neck. This prevents the use of the usual type of socket member which is of i a diameter only slightly exceeding that of the stopper, and requires a socket member of suflicient proportions to practically fill the neck.

.A'ccording to our invention we provide an improved socket member of this type which is of cheap and simple construction, which permits a proper finish of the exterior parts,

and which preventsthe retention of any water' within the bag when the latter is emptied.

According to the accompanying drawings wherein we have illustrated one form ofour mvention,Figure 1 is a sectional View of a water bag provided with our improved.

socket member, the sectionbeing taken along the major diameter of the socket member. Fig. 2 is a similar view taken along the minor diameter of such member. Fig. 3 is aplan-view'of thesocket member. Fig; 4 is a [View showing the two parts of which the member is constructed detached. Fig. 5 is a'sectional view of a modified form.

Application filed July 13, 1908. Serial-No. 13,216.

bythe molding process hereinbefore referred I to, such water bag having an enlarged neck B and a short funnel portionC.

D is the usual stopper which is adapted to screw into the socket member E. The socket member E is formed in two sections, the top section F being formed of a flat plate G, the

.middle portion of which is drawn downwardly in a suitable press to form a tubular extension H, the side walls of which are screw-threaded and the bottom of which is provided with an inturned flange I. The top plate is also flange J which is 'designed to engage the lower section K. The latter section is formed cup-shape and provided with internally bent side walls L. At its middle the bottom of the cup K is apertured at M to register with the opening within the flange I of the upper member F, around which opening the parts are connected. This may be done by means of interlocking flanges on the upper and lower members, such as are shown for instance in Figs. land 2, wherein thebottom wall of the lower member L is formed with. a flange 0 which is turned over the flange I of the up per member. The flanges-may be soldered in this position if desired, although this will not ordinarily be necessary. Or the construction shown in Fig. 5 may be adopt-ed wherein the two parts are soldered together. By any of the construct-ions just described a seat for the stopper is formed at the bottom of the'socket member. In connecting the parts the lower member K is inserted within the flange J of the upper member F and the flange is then rolled down so as to unite the parts as shown in 1 and 2. The outwardly turned upper edge of the lower member L permits the flange J to make a secure joint between the parts by simply turning it inwardly as shown.

The shape of the socket member may be varied considerably. Usually it will have an oval form so as to conform as far as possible to the fiat shape of the bag. It may be attached to the bag in any desired way, as for instance by winding the neck of the bag with wire such as N, the wire being covered by a suitable tape or binding P.

When the two sections of the socket memformed with a peripheral,

ber areunited an extremely strong and light no leakage into the interior of the socket member will be possible. The construction prevents any possible distortion of the wall L by the pressure of the uniting wire N or by the shocks and strains of use. A tight joint between the bagand socket member is thus always assured.

Another important feature of the invention is that it is possible to finish the socket member by nickel plating it or by other means without an excessive cost. It is practically necessary that the wall L shall be free from plating in order that a tight joint may be secured between the bag and the socket member. On the other hand, it is desirable to nickel the top plate G and the tubular member H. By the present construction the top section F can be nickeled separately while the lower section is left without finish;

If the wall L and the top plate G were formed in one piece, it would be necessary to nickel the entire structure and to subseuently remove the plating from the wall L. This would involve a relatively large and unnecessary expense.

While we have shown in detail but one form of our invention it will be understood that we do not wish to be limited, thereto as various modifications may be made therein without departing from the invention.
